Davis,\nof Los Alamos National Laboratory report:\n\nThe RAPTOR network of robotic optical telescopes made observations of Swift\ntrigger 534402 (Yershov, et al., GCN 13796).  The burst location was within\nthe field of our wide-field monitor located in Maui, HI, which began a 10 s\nintegration of the location at 05:16:05.26 UT, 1.0 s before the Swift trigger\ntime and during the gamma-ray emitting interval.  The next 10 s exposure began\nat 05:16:23.26, 17.0 s after the Swift trigger and covering the peak emission\ndetected by the BAT (Markwardt, et al., GCN 13807).  The optical counterpart\n(Levan, et al., GCN 13802) was not detected above our 3-sigma limiting\nmagnitude of 10.5 based on a comparison of our unfiltered image to the\nTycho-2 V-band catalog.",
